专业术语—口腔生理学术语C4(英文详解)
Covalent bond - a strong bond between atoms formed by sharing outer electrons. When an atom has 8 outer electrons it is stable. Those which naturally have 8, like neon and argon gasses are quite unreactive. The carbon atom has 4 outer electrons and therefore needs 4 extra electrons to be stable. Four hydrogen atoms make a good partnership 1 for carbon,(CH4, C2 H6 ... etc) hence hydrocarbons,(saturated with hydrogen atoms) are quite stable, insoluble and unreactive. One oxygen atom (outer shell has 6 electrons) and two hydrogen atoms (H2O) also makes a stable arrangement, although not as stable as the hydrocarbon 2, family as the water molecule 3 is a little unbalanced, providing hydrogen bonds and other unusual properties of biological importance, such as its ability to hold other molecules 4 in a solution.
Cusps - peaks or raised areas of a tooth which usually fit into a fossa on the opposing tooth.
Cytokines -chemical messengers that allow neighbouring cells to communicate with each other. They are paracrine messages as distinct from endochrine or hormonal 5 messengers. There are several main families of cytokines including growth factors , neurotransmitters, , lymphokines and many others. The method of communication involves detection of the chemical message, a ligand , by receptor proteins (for example an integrin on the cell membrane 6 of the receiving cell. The result of the message is a shift in the level of gene 7 expression or the expression of new genes 8 and altered cell behaviour. Cytokines are complex as they sometimes inhibit 9 and/or facilitate the actions of each other.
Cylasm - the contents of the cell, not including thenucleus.
Cytoskeleton - a system of fine filaments 10 which cross the cell in all directions, helping 11 toand keep or change its shape. There are three main types of filaments; in order of decreasing size they are, microtubules, microfilaments and intermediate filaments.
Cytotoxins - products released by bacteria which are toxic 12 to other living cells.
